[0002] Agriculture is one of the main industries in our country. Before planting, it is best to test the actual soil conditions so as to adjust the crops planted according to the soil conditions. At this time, it is necessary to sample and analyze the soil, and a soil sampler is needed when sampling the soil.

[0003] Currently, the common soil sampler consists of a sampling tube and a connecting handle. When in use, the sampling tube is inserted into the soil to a certain depth, and then the sampler is shaken and pulled upward to take out the soil. Although the soil in the sampler is a whole at this time, it is easy to break when the soil is pulled out of the sampling tube, and some of the soil will fall and mix together. When it is necessary to test the soil at different depths of the same soil sample, it is easy to confuse it, and the mixed soil will also affect the final test results. For this reason, we propose a soil sampling device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] Reference Figure 1-5 A soil sampling device includes a sampler body 1, the sampler body 1 includes a sampling barrel 2, a plurality of collecting tubes 3 are arranged in the sampling barrel 2, an auxiliary structure 4 is arranged at one end of the sampling barrel 2, the auxiliary structure 4 includes a cover 401, the cover 401 is located at the other end of the barrel body 201 and is threadedly connected thereto, an auxiliary component 402 and two limiting components 403 are arranged on the cover 401, and the two limiting components 403 correspond to the auxiliary component 402, the two limiting components 403 are fixedly connected by two fixing components 404, and the fixing component 404 is composed of bolts and nuts.

[0029] The sampling tube 2 includes a tube body 201, and a blade body 202 is provided at one end of the tube body 201. The setting of the blade body 202 is conducive to the insertion of the sampling tube 2 into the soil, and can also limit the collecting tube 3. One end of the blade body 202 is fixedly connected to a connector 2021, and the connector 2021 is threadedly connected to the tube body 201. The inner diameter of the tube body 201 is the same as the outer diameter of the connector 2021, the inner diameter of the tube body 201 is the same as the outer diameter of the collecting tube 3, the inner diameter of the collecting tube 3 is the same as the minimum inner diameter of the blade body 202, and the outer diameter of the blade body 202 is the same as the outer diameter of the tube body 201.

[0030] The auxiliary component 402 includes a threaded rod 4021 threadedly connected to the cover 401, both ends of the threaded rod 4021 pass through the cover 401 and extend a portion, one end of the threaded rod 4021 is fixedly connected to a pressure plate 4022, the diameter of the pressure plate 4022 is the same as the inner diameter of the barrel 201, and the pressure plate 4022 corresponds to the collecting tube 3, and the other end of the threaded rod 4021 is fixedly connected to a turning handle 4023.

[0031] The limiting component 403 includes a fixed plate 4031 fixedly connected to the cover 401, one end of the fixed plate 4031 is hinged with a rotating plate 4032, the other end of the rotating plate 4032 is hinged with an arc plate 4033, a thread is provided in the arc plate 4033, and the thread corresponds to the thread of the threaded rod 4021, the thread at the threaded connection between the cover 401 and the threaded rod 4021 rotates in opposite directions to the thread in the arc plate 4033, so when the threaded rod 4021 rotates, the moving direction on the cover 401 is opposite to the moving direction on the arc plate 4033, the two arc plates 4033 can form a sleeve, and both ends of the arc plate 4033 are fixedly connected with side plates 4034.

[0032] When in use, first place the corresponding number of collecting tubes 3 into the sampling tube 2 as needed, then cover one end of the sampling tube 2 with the cover 401 and rotate it to fix the cover 401 on the sampling tube 2, turn the handle 4023 to make the threaded rod 4021 move downward with the pressure plate 4022 until the pressure plate 4022 presses on the uppermost collecting tube 3, thereby limiting the collecting tube 3, and then rotate the rotating plate 4032 to make the arc plate 4033 sleeve on the outer surface of the threaded rod 4021, and use the fixing part 404 to fix the two arc plates 4033, which is to make one end of the bolt pass through the two side plates 4034 in turn and fix them with nuts.

[0033] After installation, aim the sampling tube 2 at the ground and insert it. At this time, the soil will enter the sampling tube 2. When inserting it, hold the handle 4023 and turn it back and forth. Since the threads on the cover 401 and the curved plate 4033 rotate in opposite directions to the threads on the threaded rod 4021, the movement directions of the threaded rod 4021 and the cover 401 and the curved plate 4021 are opposite, thereby canceling each other out. When the soil enters the sampling tube 2, it also enters the collecting tube 3 until the sampling tube 2 can no longer move down. At this time, the sampler is pulled out of the soil.

[0034] Next, the blade is rotated to separate it from the cylinder body 201. This is to loosen the two fixing parts 404 to separate the arc plates 4033 of the chain. Then the handle 4023 is rotated again to move the threaded rod 4021 with the pressure plate 4022 downward, thereby pushing the collecting tube 3 out of the cylinder body 201. Each time a collecting tube 3 is pushed out, it is separated from the other collecting tubes 3 by a knife, and a number is written on the outer wall of each collecting tube 3 after separation to prevent confusion. In this way, the taken out soil will not fall and mix, which is conducive to detection.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
